Well, we do see these requests here on a regular basis, but not usually from the same people over and over again. I think it's a stage in one's developing musicianship many of us go through.... from the answers that are given one usually gets not a cookie-cutter, definitive answer but a series of them, and that amounts to a wide range of different things to try.... you learn a lot by trying them, as well as learning how other, more experienced folks talk about it-- the language they use, the thought process.... makes it easier, I bet, to ask people in person.
Sometimes the request also has to do with people who play hour after hour at home alone-- you know the syndrome-- locked away in their bedroom and afraid to let anyone hear them or just absorbed in the rich sound and feel of the wood. A lot of beginning guitar players seem to get lost there-- more guitarists than other instruments' players I mean-- and these folks honestly may not have any experience playing with other folks and swapping approaches "on the fly."
Others lack transposing skills and are actually looking for that kind of help. They may hear a song in one key and get chords to it in another key, and not have the ear to realize there are two keys there-- that the chords they have will actually work if they just sing it in a different key from the one stuck in their heads off a recording.
